A sand washing machine for recycling construction waste

Abstract

This utility model discloses a sand washing machine for recycling construction waste, belonging to the technical field of sand washing devices. It includes a filter tank with a coarse filter plate clamped to the top. A vibrator is bolted to one side of the coarse filter plate, and a support plate is bolted to the lower surface of the vibrator. The support plate is bolted to the outer wall of the filter tank. Two water inlet pipes are fixedly installed on both sides of the top of the filter tank near the partition. Two rotating wheels are rotatably connected to the left bottom plate of the filter tank via bearings, and soft magnetic sheets are clamped onto the rotating wheels. The coarse filter plate first filters out ultra-coarse waste. The filtered material flows away below the partition, and water is added through the inlet pipes to flush it, accelerating the material's descent.

A fixing spring is fixedly installed on the surface of the anti-blocking rod, and the fixing spring is fixedly installed on the outer wall of the discharge pipe.

[0004] The above-mentioned patent has the following shortcomings: when processing construction waste, it is necessary to filter it in advance; otherwise, the steel scraps in the sand and gravel will damage the subsequent equipment to a certain extent, reduce the service life of the equipment, and increase the cost of use.

[0005] To address this, a sand washing machine for recycling construction waste is proposed, capable of processing various types of construction waste sand and gravel, and featuring a built-in combined filtration and sand washing structure. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a solution that can effectively solve the problem of complex composition of construction waste, so that it can be used without pretreatment, and has a built-in combined filter and sand washing structure, making the sand washing process more convenient.

[0007] To address one or more of the above-mentioned defects or improvement needs in the existing technology, this utility model provides a sand washing machine for recycling construction waste, including a filter tank. The filter tank has a hollow internal structure, and a partition is fixedly installed in the middle of the filter tank, dividing the filter tank into left and right parts. The left and right parts of the filter tank are connected to each other from the bottom of the partition. A coarse filter plate is snapped onto the top of the filter tank, and a vibrator is fixedly installed on one side of the coarse filter plate by bolts. Two water inlet pipes are fixedly installed on both sides of the top of the filter tank near the partition. Two rotating wheels are rotatably connected to the bottom plate on the left side of the filter tank through bearings, and soft magnetic sheets are snapped onto the rotating wheels.

[0008] In some embodiments, a support plate is fixedly connected to the lower surface of the vibrator by bolts, and the support plate is fixedly connected to the outer wall of the filter tank by bolts.

[0009] In some embodiments, a sand washing tank is bolted to the side of the filter tank away from the vibrator.

[0010] In some embodiments, a wheel bucket seat is fixedly installed on the top of the outer wall of the sand washing tank by bolts. The wheel bucket seat is clamped with a bearing, the bearing is welded with a wheel bucket, the bearing is driven by a belt, and the other end of the belt is driven by a power wheel.

[0011] In some embodiments, the drive wheel is rotatably connected to a motor via a rotating shaft, and a support frame is fixedly connected to the lower surface of the motor.

[0012] In some embodiments, a fine sand collection box is fixedly installed on one side of the sand washing tank by bolts.

[0013] In some embodiments, a sludge drain pipe is fixedly installed on the other side of the sand washing tank by bolts.

[0014] In some embodiments, a groove is provided between the outer wall of the sand washing tank and the sludge drain pipe, and a baffle plate is slidably connected between the sludge drain pipe and the outer wall of the sand washing tank through the groove, with a handle welded to the top of the baffle plate.

[0015] In summary, the technical solutions conceived by this invention have the following beneficial effects compared with the prior art: This utility model discloses a sand washing machine for recycling construction waste. It first filters out ultra-coarse waste (such as rebar ends and large pieces of concrete) through a coarse filter plate. A vibrator vibrates the coarse filter plate to prevent clogging and accelerate material filtration. The filtered material flows away below the baffle plate, and water is added through the water inlet pipe to flush it, further accelerating the material's descent. The material then passes through two rotating impellers equipped with soft magnetic plates. As the material passes through the impellers, the water flow propels the impellers, causing the magnetic plates to rotate and adsorb rebar fragments from the sand and gravel. This combined filtration process not only reduces damage to the equipment from prolonged use but also improves the purity of the sand and gravel.

[0016] This utility model discloses a sand washing machine for recycling construction waste. It uses motors on both sides of a filter tank to drive belt-driven bucket wheels for rotation. The slow rotation and agitation of the bucket wheels removes soil from the surface of the sand and gravel, processing materials with attached impurities. After processing, the rotation speed of the bucket wheels can be adjusted to filter out fine sand. The operation of the bucket wheels effectively reduces sand loss during washing, ensuring the quality of the finished sand.

[0017] This utility model discloses a sand washing machine for recycling construction waste. After material processing, it filters fine sand into a fine sand collection box. Once the fine sand is collected, the user can manually open a baffle plate to discharge wastewater through a sludge drain pipe. The baffle plate effectively prevents wastewater from leaking out before complete filtration, ensuring a clean working environment. The entire process makes the recycling and processing of construction waste more efficient. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Please refer to Figure 1-4A sand washing machine for recycling construction waste includes a filter tank 1, which has a hollow internal structure. A partition 20 is fixedly installed in the middle of the filter tank 1, dividing the filter tank 1 into left and right parts. The left and right parts of the filter tank 1 can be interconnected from below the partition 20. A coarse filter plate 2 is snapped onto the top of the filter tank 1. A vibrator 18 is fixedly installed on one side of the coarse filter plate by bolts. A support plate 10 is fixedly connected to the lower surface of the vibrator 18 by bolts. The support plate 10 is fixedly connected to the outer wall of the filter tank 1 by bolts. Two water inlet pipes 17 are fixedly installed on both sides of the top of the filter tank 1 near the partition 20. Two rotating wheels 3 are rotatably connected to the bottom plate on the left side of the filter tank 1 by bearings. Soft magnetic sheets 4 are snapped onto the rotating wheels 3. The vibrator 18, connected to the coarse filter plate 2, vibrates the coarse filter plate 2. During operation, the coarse filter plate 2 first filters out overly coarse waste materials (such as rebar ends and large pieces of concrete). The vibrator 18 vibrates the coarse filter plate 2 to prevent clogging and accelerate material filtration. The filtered material flows away under the baffle 20, and water is added through the water pipe 17 to flush it, increasing the speed at which the material slides down. Then, the material passes through two rotating wheels 3, on which soft magnetic sheets 4 are installed. When the material passes through the rotating wheels 3, the water flow propels the rotating wheels 3 to rotate the soft magnetic sheets 4, adsorbing rebar fragments in the sand and gravel. This combined filtration process not only reduces damage to the equipment after prolonged use but also improves the purity of the sand and gravel.

[0023] In this embodiment, a sand washing tank 19 is bolted to the side of the filter tank 1 away from the vibrator 18. A wheel bucket seat 16 is bolted to the top of the outer wall of the sand washing tank 19. A bearing 6 is clamped to the wheel bucket seat 16, and a wheel bucket 5 is welded to the bearing 6. A belt 7 drives the bearing 6, and a power wheel 13 drives the other end of the belt 7. The power wheel 13 is rotatably connected to a motor 8 via a shaft, and a support frame 9 is fixedly connected to the lower surface of the motor 8. The filtered material falls into the filter tank 1 with the water flow. The motors 8 on both sides of the filter tank 1 drive the wheel bucket 5 to rotate via the belt 7. The slow rotation and stirring of the wheel bucket 5 can peel off the mud from the surface of the sand and gravel and treat the material with attached impurities. After processing, the fine sand material can be filtered out by adjusting the rotation speed of the wheel bucket 5. The operation of the wheel bucket 5 can effectively reduce the loss of washed sand and ensure the quality of the finished sand.

[0024] In this embodiment, a fine sand collection box 12 is bolted to one side of the sand washing tank 19, and a sludge drain pipe 11 is bolted to the other side of the sand washing tank 19. A groove is provided between the outer wall of the sand washing tank 19 and the sludge drain pipe 11. A baffle plate is slidably connected between the sludge drain pipe 11 and the outer wall of the sand washing tank 19 through the groove. A handle 15 is welded to the top of the baffle plate 14. After the material processing is completed, the fine sand is filtered into the fine sand collection box 12. After the fine sand is collected, the user can pull up the handle 15 to open the baffle plate 14 and discharge the wastewater through the sludge drain pipe 11. The baffle plate 14 effectively prevents wastewater from leaking out before complete filtration, ensuring a clean working environment. The entire process makes the recycling and treatment of construction waste more efficient.

[0025] In this example, a sand washing machine for recycling construction waste operates by first filtering out coarse waste (such as rebar ends and large pieces of concrete) using a coarse filter plate 2. A vibrator 18 vibrates the coarse filter plate 2 to prevent clogging and accelerate material filtration. The filtered material flows away under the partition plate 20, and water is added through the water inlet pipe 17 to rinse it, further accelerating the material's descent. The material then passes through two rotating wheels 3, each equipped with a soft magnetic sheet 4. As the material passes through the rotating wheels 3, the water flow causes the wheels 3 to rotate, adsorbing rebar fragments from the sand and gravel. The filtered material falls into the filter tank 1 with the water flow. Motors 8 on both sides of the filter tank 1 drive the bucket wheels 5 to rotate via belts 7. The slow rotation of the bucket wheels 5 agitates and removes soil from the surface of the sand and gravel, processing any attached impurities. After processing, adjusting the rotation speed of the bucket wheels 5 filters out fine sand into a fine sand collection box 12. After the fine sand is collected, the user can manually open the baffle plate 14 to discharge wastewater through the sludge drain pipe 11. The combined filtration of coarse filter plate 2 and rotor 3 not only reduces damage to the equipment after long-term use, but also improves the purity of sand and gravel, making the device highly adaptable to various construction waste sand and gravel.

Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
